Claims.
My invention relates to gang vibrator mechanisms and like devices.
My invention relates more particularly to vibrator mechanisms capable of being attached to screed operating machines or other road machinery for use in compacting unset cement or similar road building material.
The principal object of the present invention is to provide a vibrator mechanism capable of being attached to road building machinery or similar machinery.
A further object of the invention is to provide such a vibrator mechanism capable of bein operated from the road machine and capable of adjustment upon the same.
A further object of the invention is to provide an improved gang vibrator mechanism of the class described which will include a plurality of vibrator units adapted to be moved about and controlled by an operator from a platform of the screed operating machine or other road building machine to which the same is attached.
A further object of the present invention is to provide an improved vibrator mechanism of the type described, so constructed and designed that a single operator may easily direct the operation of a plurality of vibrator mechanisms and. con trol the same as a single unit or control the individual vibrators or any number thereof as desired.
A further object of the invention is to provide an improved construction of gang vibrator mechanism capable of being mounted upon a road building machine and capable of easy and simple manipulation back and forth upon the same to determine the position at which the operation of the vibrators is to be effected.
A further object of the invention is to provide an improved construction of gang vibrator mechanism capable of attachment to a road machine and capable of being operated about a pivot by means of a hand lever and an improved construction of counterweights.
In the improved construction which I have pro- Vided, I employ a machine that may include a series of five to nine direct driven electric motor vibrators weighing approximately 100 lbs. each. These vibrators may be hung from a pipe or other support which is suspended from the finishing machine and can be raised and lowered into the unset concrete very readily by the operator of the finishing machine. With an arrangement like this, the entire slab of the road from one side to the other will be thoroughly vibrated internally,
giving highly beneficial results in lasting quality and proper concrete compaction.
Other objects and advantages will be apparent from the following description wherein reference may be had to the accompanying two sheets of drawings upon which Fig. 1 is an end elevational view of a road building or finishing machine with my improved vibrator unit mounted thereon;
Fig. 2 is a plan view of the same mounted upon the rear portion of the machine;
Fig. 3 is a side elevational view of the vibrator unit shown mounted upon the machine with portions of the same broken away to more clearly show other parts;
Fig. 4 is an enlarged sectional view illustrating generally the type of vibrator employed; and
Fig. 5 is a view in perspective of a modified form of vibrator motor support member.
In the embodiment of the invention which I have chosen to illustrate, I have shown a portion of the finishing machine or other road building machine l0 supported by the wheels l6 upon the side frames l2 and I4 within which the road bed is laid.
The frame of the vibrator unit may be generally an elongated platform l8 formed with downwardly directed side portions l9 and 2|. Each of the side members may carry a plurality of rollers 23 adapted to ride in a pair of channel members 20 and 22 mounted on the platform of the screed. Stop members (not shown) are provided at the outer ends of the channel members for preventing the rollers from running off the channel members 20 and 22. The platform l8 of the vibrator unit may be formed with a plurality of upwardly directed standards 26 which support a horizontal rod 28 at their upper end; The rod may be suitably journalled in the bearing portions 30 of the standards 26 and be capable of rotation therein. I provide a plurality of arms 32 extended outwardly from the horizontal rod 28 adapted to support at their outer end and parallel to rod 28 a second parallel rod member 34. The rod member 34 may have a plurality of downwardly projecting supports 36 secured thereto in pairs of two at spaced intervals from one end of the rod to the other. The supports 36 are pivotally connected upon the opposite sides of a vibrator motor housing 38 and thus support the same hanging suspended therefrom.
The vibrator units generally may include the motor 38, a flexible shaft 40 and a vibrator unit 42. These vibrators may be of the usual type shown and described in my copending application for patent on vibrator, Serial Number 18,2 69. Since that application gives a complete description of the construction of the same, further details will not be given herein. It is sufiicient to state that the unit generally comprises a flexible shaft-member 44 driven bysthe motor 38 and extending downwardly to the vibrator housing 46 in a flexible shaft housing 48. The tip 50 of the flexible shaft is in driving engagement with an offset weight member 52 which may be mounted in suitable bearings 54 and 56 adjacent the upper and lower end of the shell or housing 46. Thus, in the construction which I have shown I have placed vibrator units approximately two or three feet apart to get sufficient vibration for perfect compaction throughout the width of the road that is being laid. The motors may be of any suitable or desirable style and description. However, I have found that by using a 1 H. P., 220
approximately 10,000 R. paction has resulted.
In order to swing the vibrators about, as indicated' by the dotted' lines in Fig. 3, I have provided a lever 60 rigidly fastened to the horizontal rod 28 and provided withthe usual spring pressed dogto engage in the notches 62 attached toone of the rigid arms 26' of the yibrator platform l8. By means of the weights W suspended to the rear of the horizontal rod 28 upon the arms 64, it is easy for an operatorto swing the entire gang of vibrators up and down and back and forth by means of the lever 60. In Fig. 5, I have illustrated a modified form of support arm 3211.. By employment of the arms 32a rigidly connected to the horizontal rod 28, the additional horizontal rod member 34 may be eliminated. Each'of the motor driven vibrator units 32b may be pivotally supported between the arms 32c oftlie support 3201. and be operated as a unit by the manipulation of lever 60. From the above and foregoing description it P. M., very good comwill be apparent to those skilled in the art that I tain desired distance back of the road building machine. Control switches for the individual motors may all be extending to a desired loca ti'on on the finishing machine so that theoperator can control the operation of any or all the vibrators at will.
While I have illustrated and described a specific embodiment of the invention, I do not wish to be limited in any particular to the detailed construction shown. Rather, what I desire to secureandprotect by Letters Patent of theUnited States is:
1. Apparatus of the class described capable of being supported upon aroad buildin machine, including a pair of spaced parallel channel members mounted in a horizontal plane on said road building machine, a truck mounted forback and forth movement between said channel members, a pluralityof rollers upon opposite sides'of said truck riding" in's'aid channel members, a frame carried by said truck, a horizontal bar journalled H in said frame, a plurality of rigid arms extended from said horizontal bar, ahorizontal shaft carried thereby, and a plurality of vibrators suspended from said horizontal shaft and pivotally supported thereby, said vibrators being adapted for horizontal adjustment to various positions relative to the road building machine, said adjustment being obtained from the back and forth movement of the truck.
2. Apparatus of the class described comprising a movable support capable of attachment to a road building machine and movable in a horizontal plane, rollers provided for said movable support, a horizontal shaft pivotally mounted in said support, a plurality of outwardly extending arms on said shaft, asecond horizontal shaft journalled in said arms and a plurality of vibrator members pivotally supported by said second shaft and suspended therefrom, said vibrator members including a motor, a flexible shaft driven thereby and a vibrator casing at the lower end of said shaft, and being adapted for horizontal adjustment to various positions relative to the road building machine, said adjustment being obtained by moving the movable support.
